Description

BACKGROUND OF THE INVENTION

The present invention relates to a method and apparatus for searching and retrieving architectural information for design of architectural projects and for assisting in the selection of specific materials and items for use in architectural projects.

A variety of systems have been developed to assist in architectural project design. One such system is disclosed in U.S. Pat. No. 4,964,060 to Hartsog. Hartsog discloses a computer aided building plan review process which evaluates the compliance of development plans with building regulations and codes. The process will output a list of code non-complying items. It also designs working drawings and specifications using an automated computer process. The system further includes animated viewing of sites and structures and can generate detailed shop and sub-drawings, contracts, work schedules, lists of suppliers with availability dates, and check-off lists for inspections, required materials and the like.

A second related system is disclosed by Normann, et al., in U.S. Pat. No. 5,557,537. Normann discloses computerized methods and devices for designing and editing a distribution system for a building. Elements of the distribution systems and requirements of relevant standards are stored in the computer's memory. Building parameters and the standards to be followed are input by the user. The system computes the layout needed to comply with the selected standard and prints out a hard copy of the design layout which can include a listing of the elements needed to complete the system.

These prior systems require the user to input extensive data in order to obtain information. Further, these systems do not include a mechanism for providing access to all of the available codes and regulations that a designer would need in order to have a plan approved.

SUMMARY OF THE INVENTION

It is therefore, an object of the invention to provide a method and apparatus for searching and retrieving architectural information for enabling design of architectural projects such that a user can ensure early in the design process that all applicable regulations will be followed.

It is a further object of the invention to provide a system in which the user is not required to input design data in order to gain access to required information.

To achieve the objects in accordance with the purpose of the invention, as embodied and broadly described herein, an aspect of the invention provides the user with an option of performing a resource search or a customized search. The resource search is able to retrieve all information from the stored resources regarding a requested term. The customized search assists the user in selecting a particular item or building material based on criteria selected by the user.

In a further aspect, the invention provides an architectural design system that assists an architect in designing a building feature. The system includes a resource storage subsystem for storing building code resources, accessibility resources, and format resources. A search term storage subsystem is included for storing a plurality of predefined search terms corresponding to physical environmental features, assembled building components, and building elements. The system further includes a display subsystem having a search term display area for displaying one or more search terms selected by the user from the plurality of search terms stored in the search term storage means. The display subsystem further includes a resource selection display area for displaying one or more of the resources stored in the resource storage means. Finally, the display subsystem includes document viewing for displaying text from the selected resource. A user interface subsystem is included for selecting a term from the plurality of search terms stored in the search term storage subsystem and at least one resource from the plurality of resources stored in the resource storage subsystem. The system further includes processer for reviewing the selected resource to find information relative to the selected search term. The information found by the processer means is then displayed by the document viewing window.

In another aspect, the invention provides a method for designing a building feature using a computerized tool. The method includes the steps of selecting a search term from a plurality of pre-defined search terms corresponding to physical environmental features, assembled building components, and building elements, and determining whether desired resources from a resource storage means are enabled or available for use. Resources are considered to be enabled if they include information related to the selected search term. The desired resources may include building code resources, accessibility resources, and format resources. The method further includes the step of selecting at least one enabled resource if an enabled resource exists. The method further includes the step of viewing of a resultant display of the selected enabled resource in a document viewing window on a display mechanism. Finally, the method includes the steps of selecting a hypertext section from the resultant display in the document viewing window and creating a resultant document and reviewing the resultant document in the document viewing window.

The accompanying drawings, which are incorporated in and constitute part of this specification, illustrate one embodiment of the invention and, together with the description, serve to explain the principles of the invention.

For this purpose, as shown in FIG. 2C, custom storage subsystem 800 includes category storage 810, subcategory storage 820, criteria storage 830, and item storage 840. These sections are linked to one another such that the selection of a category will extract specific subcategories, the selection of a subcategory will extract particular criteria, and the selection of particular criteria will extract items meeting the criteria.

FIG. 5 illustrates the components of display subsystem 400. Search term display area 430 displays the aforementioned options included in the physical environmental features section 310, assembled building components section 330, and building elements section 350. Resource selection display area 420 displays the options enumerated for resource storage subsystem 200 including the building codes resource section 210, accessibility resource section 220, directories section 230, formats section 240, and graphic resource storage section 250. A document viewing window 410 displays the data located by the processer 100 in response to a user inquiry. A tools display area 440 displays some additional available tools. Such tools may include a help button for generating online help information, an about button for generating information about the software, and a clear button for deselecting all of the selected buttons. Additionally, an exit button may be provided for exiting the program. A navigation tools display 450 includes an area showing tools available for navigation between documents. Such tools preferably include a mechanism for moving forward and a mechanism for moving backward.

Generally, in operation, a user will make an inquiry concerning the design of a specific feature. The user will select this feature from the search term display area 430. Alternatively, the user can enter the term as a key word if it is not available in the search term display area 430. Upon selection, processor 100 will access the search term storage subsystem 300. Using processing tools 130, processor 100 will disable any resources in the resource storage subsystem 200 that do not contain information regarding the selected search term. This becomes apparent to the user because the resource selection display means 420 will show the term as disabled. The user is then able to select from the enabled resources. Upon selection, a document with hypertext win appear in document viewing window 410. When the user sees the desired hypertext, the user can select the hypertext to view the referenced document. Upon accessing a document, the user can navigate between documents if other documents have previously been downloaded. Otherwise, the user can select different hypertext, select alternative resources, or enter a new search inquiry. If the user has located all the information desired, the user can then exit the program.

FIG. 6A illustrates a preferred layout for the screen display. The screen display shown displays text from a selected resource.

FIG. 6B illustrates a table viewing option that is preferably provided. When a resource includes a table, hypertext will be provided to activate the table viewing option. With the table viewer, tables of large size can be efficiently used. Scroll bars are preferably provided.

FIG. 6C illustrates an image viewing option that is preferably provided. The image viewing feature allows the user to display an image with various magnification factors. The magnification of the image can be varied, as can the magnification of small portions of the image.

FIG. 7A illustrates the customized search mode of locating information regarding a search term in assembled building components section 330. The user will preferably be provided with the option of performing either a customized search or a resource search as described above. In the example shown, wall 332 has been selected as the search term. In document viewing window 410, wall type selection criteria 610 are displayed. The user can either select an enabled resource as described above or can select specifications from wall type selection criteria 610. In the example shown, the user can select a subcategory from structural materials category 611, from location/function category 612 or from performance category 613. Within each subcategory the user can select desired criteria.

When criteria are selected, the bottom half of document viewing window 410 will automatically narrow down to the list 411 of particular items that satisfy the selected criteria. In tool box 412, the items are listed and navigation buttons are provided for manipulating the items. Navigation button 413 is a right arrow that allows the addition of items to the list. Left arrow 414 allows the deletion of items from the list. Save button 415 allows the list to be saved to a disk. Erase button 416 erases all selections from the list. Report button 417 creates an 8½×11 inch detailed report for the items and print button 418 allows the items to be printed.

As shown in FIG. 7B, when presented with wall type selection criteria 610, the user can select a subcategory within a category. In this instance, under the structural material category 611, the user has selected subcategory 611a which presents a pull-down menu 700 of specific materials. Here, "steel stud" has been selected and the list 411 is formed to include all walls that are formed from steel stud material. The user can then proceed to thickness subcategory 611b. When a specific thickness is selected, those entries not having such a thickness will be eliminated from the list in bottom half 411. Progressively, by selecting specific criteria from each subcategory, the user can have entries deleted automatically to create a manageable list. FIG. 7C further illustrates the process of narrowing the list based on the thickness 611b of the wall. Pull down menu 701 is provided which includes specific thicknesses from which a user can select. Once a particular thickness is selected, the list available of items in section 411 is again narrowed. FIG. 7D shows the selection of location subcategory 612b. A specific location can be selected from pull down menu 702 and the list 411 is further narrowed. FIG. 7E displays the criteria 703 under the fire rating subcategory 613a. FIG. 7F illustrates the criteria 704 under sound rating subcategory 613b.

After the list 411 of possible selections has been narrowed through the process of selecting criteria from each subcategory as described above, the user can select one particular item. To display more information about the selected item, the user can double click on the item and as shown in FIG. 7G, and can view an information dialog box 710 for that item. Box 710 includes a plan diagram 711 of the selected item and written information 712. In this example, the written information includes a list of wall layers. Box 710 also includes UL design number button 713 and STC number button 714. When either button 713 or 714 is activated, the test information 714 for the selected item appears on the screen as shown in FIG. 7H. Additionally, if a user double clicks on diagram 711, the diagram is reformatted to insert an autocad drawing 716, as shown in FIG. 7H.

FIG. 8A illustrates the steps that a user follows when searching for information. The process begins at step S00. The user decides whether to search a term in step S10. If the user decides to search a term, the user selects the term in step S20. The user selects the term from the options in the search term display area which include those previously described in the physical environment section 310, assembled building components section 330, and building elements section 350.

The procedures performed by the system in step S20 are further described in FIG. 9A. The user inputs the selection in substep S22. Upon selection in substep S24, processing tools 130 determine whether any of the resource options in storage subsystem 200 contain information about the selected term. If the resources do not contain information regarding the selected term, the resources are shown as disabled on display subsystem 400 in substep S26.

To obtain information regarding a specified search term, the user has an option of conducting a resource search or a customized search. As shown in FIG. 8A, the user can select to perform a custom search in step S200 or a resource search in step S300. Alternatively, the user can refuse both searches and elect to continue the search in step S150 by selecting another search term in step S10 or terminating the inquiry. Upon completion of a customized search in step S205 or a resource search in step S310, the user can select to perform an additional search in step S140 or terminate the inquiry.

If the user decides to perform a resource search in step S310, the method depicted in FIG. 8B will be implemented. In step S330, the user determines whether the desired resources are enabled. If the desired resources are not enabled, the user can go to step S130 and either quit or return to step S110 to search for a new term. However, if the desired resources are enabled, the user selects the appropriate resource in step S340.

The procedures followed in step S340 are further detailed with reference to FIG. 9B. After user selection in substep S342, retrieving tools of processor 100 retrieve applicable information in substep S344. Document display 410 will display the appropriate information as determined by processor 100 in substep S346.

Returning to the main resource search routine of FIG. 8B, the user views the display in step S350. In step S360, the user determines if the document display contains the desired hypertext. If the desired hypertext is not provided, the user can go to step S120 and quit or select a new resource or search a new term. If the desired hypertext is provided, the user moves to S370 and selects the hypertext.

The steps followed by the system when the user selects hypertext are further described with reference to FIG. 9C. In substep S372, the user inputs the hypertext selection. Upon selection of the applicable hypertext, retrieving tools 120 retrieve the appropriate information from the storage means in substep S374 and display the information on display mechanism 400 in substep S376.

Returning to the main resource search flowchart of FIG. 8B, in step S380, the user views the displayed document. In step S390, the user determines whether navigation is desired. If only one document has been downloaded or if the user chooses not to navigate, the user moves to step S110 either to quit, select new hypertext, select new resources, or search a new term. If previous documents have been downloaded, the user can continue to navigate for as long as desired in S400.

The navigation process is described in further detail with reference to FIG. 9D. In substep S402, the navigation options are displayed as navigation tools 450 on display mechanism 410. In substep S404 the user inputs a navigation option via user interface 500. In response to this input, navigation tools 110 of processor 100 perform the navigation operation in substep S406. In substep S408, display mechanism 400 displays the document resulting from the navigation. When the user chooses to exit, the user can quit at step S410 and exit.

If the user elects to perform the customized search of step S205 in FIG. 8A, the main customized search routine depicted in FIG. 8C will be executed. The type selection screen 610 is displayed in step S210. Along with type selection screen 610, a list of available items 411 is provided as described above. In step S215, the user determines whether to reduce the list size. If the user chooses to reduce the list size, a list narrowing procedure is implemented in step S225. This procedure will result in the selection of a specific item. Alternatively, the user can select the item step S220 without narrowing the list. In step 230, the user has the option to quit or to obtain more information on the selected item. If the user seeks additional information, this procedure is performed in step S235 with the aid of retrieving tools 120. In step S240, the user can exit or return to step S10 to search additional terms.

FIG. 10A shows the substeps involved in the process of narrowing the list 411 of items. In substep S250, the user inputs a subcategory selection. Retrieving tools 120 retrieve a pull down menu from custom storage subsystem 800 in substep S255. The pull down menu is displayed on display mechanism 400 in substep S260. Upon viewing the menu, the user inputs selected criteria in substep S265. As a result of the selection, processing tools 130 eliminate nonconforming list items in substep S270. In substep S275, the user has the option of whether to reduce the list further by specifying additional criteria. If the user elects this option, the process returns to substep S250 so that the user can make a subcategory selection. Alternatively, the user may believe the list has been narrowed sufficiently and may choose to select a specific item on the list in substep S280. If such a selection is made, the process returns to step S230 in the main customized search routine of FIG. 8C. If the user neither selects an item or narrows the list, the user can return to step S10 to search additional terms or exit the routine.

FIG. 10B illustrates the process of obtaining information from step S235 in the main customized search routine of FIG. 8C. In substep S287, the user double clicks on the selected item. In response to the user input, the retrieving tools 120 retrieve the info in substep S288. In substep S289, the information is displayed on display subsystem 400. In substep S290, the user may elect to obtain additional information in the form of an AutoCAD drawing. To obtain this information, the user selects the diagram in substep S291. In response to the selection, retrieving tools 120 retrieve the AutoCAD drawing from the customized storage subsystem 800 in substep S292. The drawing is displayed on display mechanism 400 in substep S293. Subsequently, in substep S294, the user can elect to search for additional terms by returning to step S110 or the user can exit.
